Several editors have previously mentioned they would like to include pressing info. Could MB simply lol add “Medium ID Codes” or words to that effect at the bottom of the Additional Information box on the enter release page? Aside from adding a meaning for this in the documentation, it would need no further explanation at this time. Those of us who would use it can figure out the matrix-variation and IFPI codes that we see there. While Discogs is helpful, it is not 100%. Editors could readily glance at the info without having to go through copious edit notes. It would not need to be data base searchable. Each additional entry could just be stacked underneath the last.
Ho Ho Ho & TTFN
